Amazon Q Developer

Amazon Q Developer is a software development assistant from AWS that spans the IDE, the command line, and the AWS console. On the IDE side it offers chat about your code, inline code completions, net new code generation, and scanning for security vulnerabilities, and AWS documentation also describes code upgrades and improvements such as language updates, debugging, and optimizations. For teams modernizing legacy systems, Amazon Q Developer can perform automated upgrades and conversions by generating a transformation plan and producing diffs you review before applying changes. On the terminal side AWS describes CLI autocompletions and AI chat to help with commands and workflows, and in the AWS console you can open an Amazon Q panel for contextual help. Amazon Q Developer includes a perpetual Free tier with monthly limits and a paid Pro tier with higher usage limits and access to advanced features, so practical evaluation should include your expected request volume and whether you need transformation allocations. Sign-in method matters for Free tier access in different interfaces, with AWS docs outlining how Builder IDs, IAM Identity Center, and IAM credentials map to IDE and CLI availability. For organizations, the key differentiators are tight AWS integration, security scanning, and transformation tooling, while the main constraints are account governance and making sure prompts and code access align with internal policies.
